Jean Grey as Dark Phoenix


Marvel's Strongest Heroes Who Have Not Debuted In The MCU
Sentry is reportedly coming to the Marvel Cinematic Universe in "Thunderbolts." He is a danger to himself and everyone around him.
Debuting in "Sentry," Bob Reynolds is a drug addict who gains his incredible abilities after breaking into a government lab and drinking the Golden Sentry Serum.
Reynolds gains the power of a million exploding suns, with a range of other powers, including molecule manipulation, god-like strength, stamina, reflexes, and near-invincibility.
First appearing in "X-Men" #1 by Jack Kirby, Stan Lee, and Jack Rosen, Jean Grey has several mighty psionic powers as an expert telepath and leader of Marvel's mutants.

During "The Dark Phoenix Saga," the powers of the Phoenix Force transform her into a cosmic juggernaut corrupted into killing billions with her reality-manipulating powers.
Debuting in "Fantastic Four Annual #6," Franklin Richards is born with reality-warping powers, granting him the god-like ability to manipulate molecules and matter how he sees fit.

His powers make him capable of going against any opponent and creating entire universes, with Franklin playing a pivotal role in restoring reality during the end of "Secret Wars."
Introduced in "Adam: Legend of the Blue Marvel," Adam Brashear's origins date back to the Kennedy administration, where he gained his powers in an experiment gone wrong.
Blue Marvel
Among his long list of abilities, he can manipulate, absorb, and project anti-matter. He has superhuman strength, genius-level intellect, and is practically invulnerable.
Debuting in "The Avengers" #85, Hyperion, aka Marcus Milton, is the leader of the Squadron Supreme, an analog of the Justice League.
The hero's Eternal physiology gives him powers similar to the Man of Steel, including super strength, speed, and durability, and he also possesses heat vision and super-hearing.
Like Superman, he draws his powers from the sun and is even weak against magic. Recent stories also hint that Vibranium is his version of Kryptonite.
